I e-mailed Kent admissions recently about any proposed changes to Kent 11+, and also about the arrangements where children who are not attending Kent state primaries or Kent linked independent schools sit all the papers (nvr, vr, maths, and writing task) all one day at a Saturday test centre.
Here is the answer, paraphrased.
KCC are writing the consultation document at the moment. They are looking at the practicalities of testing earlier, and whether this can be done if they still use the same number of tests (Bexley's consultation about testing before preference, which has just ended, proposes cutting the number of tests).
At the moment, KCC uses grammar schools for Saturday test centres where possible. It may well be the case that over time the numbers of children sitting the 11+ will increase, and test arrangements will change. KCC is currently dealing as best they can with a growing number of requests for consideration from children living outside Kent or attending schools outside Kent, in the context of a tight timetable and national legislation.
Normally, schools give a short break between the first two tests and a longer break after that, to allow for toilet and refreshment needs, but the length of the break, for example, may be affected by how many children need to be given these opportunities. Staff at all test centres do their best to make sure that children are comfortable when they sit down to complete a test.
The proportion of candidates who score well at the Saturday test centres is slightly higher than the proportion of those sitting it over two days at the Kent state primaries and linked independents. It is possible that this is because they would not enter another Local Authority's assessment process if their parents were not confident that they were very able., Anecdotally, some parents and teachers also feel that the challenge of taking the tests close together is motivating for certain types of children.
KCC is not proposing a change to how tests are spread out, because they can't see a way of doing it at present which wouldn' t create another difficulty.
Perhaps someone in your playground has seen the consultation document. I do not know who will get to see it or when. Does anyone out there know?
